Assessment of quantitative characters of groundnut (Arachis hypogeae.L) mutants in M3 Generation under Induced EMS Mutagenesis

DOI: 10.22161/ijeab.96.25

Abstract:
In the present study, three groundnut genotypes ICG2106, ICG5236 and ICG76 were collected from ICRISAT, Patancheru to study the mutagenic effect of EMS (Ethyl methane sulfonate) on the quantitative traits. The groundnut seeds were treated with different (0.3%, 0.4% and 0.5%) concentrations of chemical mutagen EMS and the seeds were sown in the experimental farm of department of genetics, Osmania University, Hyderabad. The ANOVA results revealed that the difference is highly significant due to the treatment of all the characters indicating that there is a considerable amount of genetic variability in the genotypes. In among the three genotypes (ICG2106, ICG5236 and ICG76), the quantitative traits were found to be higher in the genotype ICG2106 than ICG5236, ICG76 and it is also evident from the study that when the concentration of EMS increased, the mean values of all the quantitative traits decreased. It is observed that the seeds treated with 0.3% EMS and 0.4% EMS concentrations showed the highest mean values for quantitative characters under consideration. These mutant varieties can be further utilized in groundnut crop improvement programme.
